SOCHI, Russia -- McLaren will switch from Renault engines to Mercedes in 2021 after signing a new contract that will extend until 2024.
McLaren became a Renault engine customer after an acrimonious split with former works supplier Honda at the end of 2017. Since then, it has improved its form and currently lies fourth in the constructors' standings, ahead of the works Renault team but still some way off the top three teams Mercedes, Red Bull and Ferrari.
Although Ferrari has had the most powerful engine of late, Mercedes has won every championship since the introduction of the current turbo-hybrid formula in 2014 and looks set to win the title again this year.
